Is an attractive force positive or negative?

In general when the force is attractive, the potential energy is negative and as shown above force will be negative. In case of repulsion, with the same argument, the force will be positive.

Is attractive force positive?

9. When they are connected with a wire, the spheres will evenly divide the total charge. Also, an attractive force is negative, and a repelling force is positive.

Is a negative force attractive or repulsive?

If both the interacting particles are positively or negatively charged, then the force is repulsive. If both the interacting particles are of opposite charges then the force is attractive in nature.

What is an attractive force?

Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.

Why is attraction force negative?

That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational …

Is force of attraction negative?

Where F is the force, k is Coulomb’s constant, q1 and q2 are the charges on the two particles, and r is the distance between the particles. … When the charges have opposite sign, the force is attractive (negative F), while if both charges have the same sign, the force is repulsive (positive F).

What is negative force?

A negative force is the force acting on an object against the applied force. The applied force here is positive that is aimed in the right direction whereas a negative force acts in the left direction. An example of negative force is deceleration, where the speed of a moving object decreases due to gravitational force.

What is attractive force in chemistry?

attractive force – the force by which one object attracts another. attraction. affinity – (immunology) the attraction between an antigen and an antibody. bond, chemical bond – an electrical force linking atoms.

What forces are attractive and repulsive?

The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

How do you find the attractive force?

Calculate the force of attraction according to F = k * q1 * q2 / d2.
